Simplifying 10x2 + x + 21 = 0 Reorder the terms: 21 + x + 10x2 = 0 Solving 21 + x + 10x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. 2.1 + 0.1x + x2 = 0 Move the constant term to the right: Add '-2.1' to each side of the equation. 2.1 + 0.1x + -2.1 + x2 = 0 + -2.1 Reorder the terms: 2.1 + -2.1 + 0.1x + x2 = 0 + -2.1 Combine like terms: 2.1 + -2.1 = 0.0 0.0 + 0.1x + x2 = 0 + -2.1 0.1x + x2 = 0 + -2.1 Combine like terms: 0 + -2.1 = -2.1 0.1x + x2 = -2.1 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. 0.1x + 0.25 + x2 = -2.1 + 0.25 Reorder the terms: 0.25 + 0.1x + x2 = -2.1 + 0.25 Combine like terms: -2.1 + 0.25 = -1.85 0.25 + 0.1x + x2 = -1.85 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = -1.85 Can't calculate square root of the right side. The solution to this equation could not be determined.
